Wales have a fresh injury concern over No.8 Ross Moriarty with their Six Nations Championship clash with Ireland in Dublin just 10 days away.

The Gloucester back-rower picked up a knock to the shoulder in Saturday's 12-6 defeat to England at Twickenham and has been ruled out of the Cherry & Whites' Aviva Premiership trip to Worcester Warriors this weekend.

Moriarty has only recently returned to action after two spells of back problems, first picked up in the opening game of the Lions tour last summer, that has curtailed most of this season for the 19-times capped 23-year-old.
